Flame spread of droplet-cloud elements with two-droplet interaction in microgravity

This research conducted microgravity experiments to investigate the flame-spread characteristics of the fuel-droplet-cloud element with uneven droplet spacing, which is a basic element of a randomly distributed droplet cloud at the critical condition for group-combustion occurrence. Flame spread to a droplet followed by burning with two-droplet interaction was observed in microgravity to investigate the effect of flame-spread direction and local...
